Will do Niall.
That sounds interesting I'll have a read up on that but the LP pump and filter were changed before the HP pump was installed.
Also I would have a starting issue all the time if it were that. At the moment it's only with the cold weather.

I read something recently that described how the valve in the HP pump works. If the fuel pressure from the LP pump is below a certain value, the valve doesn't allow fuel into the HP compression side of the pump, but instead allows SOME fuel into the pump to lubricate it whilst cranking.
Did you change the fuel filter after changing the LP? maybe those bits of copper got into your new pump's lubrication valve, causing slow opening?
